Not able to run CSE (Cryptographic Service Commands) on S32R274RM Board

[MadharKhan]

Hi,

I am using S32R247RM Board. I would like to implement CSE on Board.
But i found CSE peripheral is disabled, when i looked in trace.

I have gone through AN4234 and AN5418 Application Notes and i understood the Commands.
but when i tried to implement it, no CSE related command is executing on board.

I tried by giving CSE_INIT(0x15) command  but this is also not running.

Do i need to add something in Lauterbach file to enable and run CSE commands?

please suggest me something that i can do to enable CSE.

Thank you.

Hi,

could you please confirm what is your part number? There are three configurations of the chip and only 'B' and 'S' configuration have CSE module.

See the datasheet, page 10, Table 2 and 3:

It's not necessary to enable the CSE. If you have the right part number, it should work without initialization.

Regards,

Lukas
